Senior software engineer — 15+ years building web applications, remotely.
01 / ABOUT
For 15+ years I've built and scaled web applications, all remote — full-stack, from schema to deploy. My home turf is high-load systems in Ruby on Rails, PostgreSQL, and Redis, with Hotwire front ends and a DevOps stack I run end to end: AWS — S3, Route 53, and Bedrock for AI — plus Kamal and Docker for zero-downtime deploys. I've built AI agents into a handful of apps — including Hermes, a personal agent gateway that runs my infrastructure and repos straight from chat — with MCP servers and multi-provider LLM orchestration under the hood. And Bitcoin is a long-running thread of its own: on-chain indexers and algorithmic trading systems on crypto perpetuals.

ExtensionDash: Tracking an Extension From the Agent
ExtensionDash records where your browser extension ranks in the Chrome and Firefox stores every day, and serves the whole history to your agent over MCP. It is free during the beta and I would like people to break it.

Stackpeek: See What a Shopify Store Is Built With
Stackpeek is a Chrome extension that names the theme and the apps behind any Shopify storefront, with the fingerprint database on the server instead of in the bundle.

McpLogs: Seeing What the Agent Actually Called
McpLogs is a mountable Rails engine that records every MCP request your app serves — arguments, response, timing — and renders your tool contract as live documentation.
04 / MY PROJECTS
Reverse Image Search Anywhere
A browser extension that reverse-searches any image across Google Lens, Yandex, Bing & TinEye in one right-click — and works on Instagram, Pinterest & canvas where the URL trick fails.
BTC Indexer
A Bitcoin blockchain indexer and on-chain metrics service.
Stackpeek
A Chrome extension that tells you which theme and which apps any Shopify storefront is running — one click, no signup. The fingerprint database lives server-side, so it grows without shipping a new extension version.
ExtensionDash
Daily rank, install and competitor tracking for browser extensions across the Chrome Web Store and Firefox Add-ons — served to the dashboard and to your coding agent over MCP from the same data.
